No issues during rip, but I received this error on every DVD disc of the 2017 Homicide box set USA.
MakeMKV 1.17.5
Drive HL-DT-ST, WH16NS60, fw 1.02

It appears that you are opening the disc processed by dvdfab/mactheripper which is know to produce damaged vob files. Errors may follow - please use original disc instead

You will also get that warning on a number of other popular series disks, like Castle. I only saw it on DVDs, but I was unable to confirm that the disks were genuine. All were bought on Amazon.

There is something about the way the disks are mastered that does not "ring true" as genuine. They ripped fine, but I still have no clue if they were actually genuine or not.

I just logged in and reported the same thing. No problems ripping them though.
